Zoltan Haindrich commented on CALCITE-2328:
-------------------------------------------
I'm not sure if this is a problem...I think even the sql standard doesn't
mention this; I have bumped into problems because of this feature when I've
used mysql (because it can convert an integer value to boolean; so if someone
leaves out a >10 condition somewhere it will just return something.....)
> Operand of Logical And/OR should support type like INT, DOUTLE not only
> Boolean

> As far as i see , MySQL support the following sql
> {code:java}
> select id, name from tb where 1 and 1;
> select id, name from tb where 1 and true;
> {code}
> However, calcite would not recognize that sql and says:
> {code:java}
> Caused by: org.apache.calcite.sql.validate.SqlValidatorException: Cannot
> apply 'AND' to arguments of type '<INTEGER> AND <INTEGER>'. Supported
> form(s): '<BOOLEAN> AND <BOOLEAN>'

> ... 27 more
> {code}
> So, I propose if we should introduce more type support for logical AND/OR
